Divergent: No War {Completed}

A story that has been told hundreds of times, credit to the original creator of this idea.
Obviously I had to take my own spin on this, so here is it; When we finished Divergent we were on a train, what if er never got on that train? What is Tris and Four never had to shut down the simulation? What if Erudite never attacked Abnegation?
We're going all the wag back to the beginning...Tris, the first ranked in her initiate class, dating her instructor and Dauntless prodigy Four. Will their relationship move on, or stay at a stand still? What about their friends; Uriah; Marlene; Lynn; Zeke; Shauna; Will; Christina and Al?
***all right go to Veronica Roth***
